Pattern is from the book Icelandic knitting using rose-pattern. The book preserves old Icelandic knitting tradition that had almost been lost. First half is a study of traditionnal rose-pattern insert knitting in Iceland. Inserts or rose-pattern inserts are knitted insoles that were worn in soft shoes made of fishskin or sheepskin. Second half are contemporary designs all based of old shoe-inserts. The author has tried to remain true to the original color schemes of the inserts she chose, and the traditionnal methods used in making them (Icelandic intarsia, i.e. intarsia knitting with garter stitch).

Pattern is in Icelandic, English, Russian (soon) and French.

The sweater is inspired by old Icelandic shoe-inserts decorated with a Högnakylfa, a sort of Icelandic spiked mace used by the trolls.
